LAV Filters - DirectShow Media Splitter and Decoders

[nevcairiel]

They do say talking about your problems helps......

[[ReX]]

Just posting this in case it's helpful to anyone having the same problem.
I was having problems with inaudible voices with 6ch AC3 in AVI container (I assume it's commonly caused by the audio not being converted to Stereo), so I thought it was LAV Audio's fault, installed ffdshow (after trying a couple of old LAV Splitter versions) and made sure AC3 was decoded using it inside of MPC-HC, now the audio worked fine.
But I didn't settle for that, I then disabled AC3 decoding in ffdshow and re-enabled it in LAV Audio, and played the file using GraphStudio, the audio worked fine too.

Turns out the culprit was actually MPC-HC's internal AVI splitter, as soon as I disabled it and let LAV Splitter do its thing, the problem disappeared.

Edit: D'oh! Same thing happens with Haali if there's 6ch AC3 on MKV.

Edit #2: Everything started to magically work again without any workarounds, I don't know what the hell happened, but I'm glad it did.

Hi, will lavfilters support decoding raw video anytime soon?

Is there anything else I have to do in order to enable MKV playback in WMP? I've installed LAV Filters 0.43 with default settings and then installed VC++ 2010 runtimes (x86 & x64). I never installed Haali or anything like that...
Just for clarification - I do not want to use WMP as my preferred PC media player but I need it to be able to play MKV as this is the way how I stream media files from Windows 7 to my Samsung TV over LAN.

The runtimes are not needed anymore.

This will make WMP/WMC recognize mkv files:

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\.mkv]
"PerceivedType"="video"

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MediaPlayer\MLS\Extensions]
"mkv"="video"

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Multimedia\WMPlayer\Extensions\.mkv]
"Runtime"=dword:00000007
"Permissions"=dword:0000000f
"PerceivedType"="video"

Thanks clsid, much appreciated. Unfortunately, though this registry hack indeed made MKV playable in WMP they're still not visible on my TV. Other containers (AVI/WMV/MP4) stream just fine, oh well, I'll have to live with portable USB HDD (un)plugging once in a while between my PC and TV for the time being...

Mercury, thanks for info but I installed AllShare software (DLNA server provided by Samsung) meanwhile and it works just fine. Its configuration is also much more convenient for me so I'll just stick with that

Strangely it worked a few times but only if I start the playback without bitstreaming and enable it afterwards in LAV Audio's config.
Is this problem happening only to me or there is some kind of general limitation? If it's not possible to make it work is it at least possible to make it not crash the player?
I have absolutely no problems with such files if I decode the stream with LAV Audio and then send it as multichannel PCM over the HDMI output of my video card.

having the same issue with .43, any other way to get bitstreaming to work?

[mindbomb]

any chance you can add a screen capture type thing to lav video?
so you can take screenshots with madvr.

[Andy o]

That's more like a renderer thing.

[ryrynz]

Use FRAPS or Afterburner for screenshots with MadVR FSE or use windowed mode.

Bitstreaming DTS in WAV works for me with MPC-HC, LAV Splitter and ReClock.
It doesn’t work if i ad LAV Audio to External Filters in MPC-HC so it gets loaded, then MPC-HC crash!

So I removed the wav headers with wav2dts and put them inside an mka with mkvmerge(I found that it also works if I just use the wav without using wav2dts as mkvmerge removes the header itself) and they play just fine by disabling lavaudio and letting ffdshow do the bitstreaming. I wonder if lavaudio has an issue with the header stripping part or maybe with the sampling rate, who knows? I just wish I could use lavaudio for this files too, since I’m already using it to bitstream DTS-HD and TrueHD to my receiver.

I just find out that disabling the "use DTD-HD framing for all DTS types" option allows lavaudio to bitstream without crashing MPC, but the sound is really pitchy, it's like 1.5x faster than it should(I've never heard the chipmunks singing a Beatles song before)

I'm probably missing something obvious but what is the advantage of bit-streaming to your receiver or TV, rather than simply decoding and sending PCM (which is supported by HDMI up to 7.1, 24 bit, 192 kHz).

Well it’s really more of a personal preference thing, but I can tell you from my own experience that for instance the PCM signal is fairly quitter than the bitstreamed one so I have to use more power to achieve the same volume, I can’t use any sound mode with PCM (PLIIx, etc), I have to rely on windows mixer that may or may not alter the original signal or use reclock with WASAPI exclusive hence adding one more link to the filter chain, you also may encounter with the Bluray swap surround thing (BS-SS) and finally I really like to see my receiver lighting up the DTS, DTS-HD logo instead of the “MULTCH IN 7.1” legend.

I have an MKV file that plays fine when using the MPC-HC decoder but not when using the LAV Video Decoder (CUVID disabled). It plays a second or so, then freezes, then continues, with a crazy graph. Here's a sample:

http://www.mediafire.com/?54asyk494jkgd20

It doesn't seem to matter if I tick or untick LAV Splitter (which is set to "preferred") within MPC-HC, although I'm not entirely sure whether it's being used or not.

Same for me if i use LAV splitter/Audio/Video + EVR, plays fine if i switch to madVR!

Nev,

This is going to sound like a rather dumb question. Using Lav + MPC HC, if I have these settings checked off only subtitles that have been flagged as forced will be presented to MPC HC, correct?



The reason why I ask, I was doing a test to see if MakeMKV was setting the forced subtitle flag. I created an mkv of District 9, and using the LAV setting above the forced subtitles appear properly in MPC HC (which would indicate that the forced flag has been properly set).

However, if I take the same mkv and dump it into mkvmerge the subtitles are not flagged as forced, just default. I am guessing now that this may just be an issue with how mkvmerge shows (possibly not keeping the flag MakeMKV creates)

[nevcairiel]

Sounds like mmg has it wrong.
You can always check in MPC-HC by going to the Filters -> LAV Splitter context menu, which would show the flags it detected.
